拉取镜像

创建启动容器

 docker run --name nginxtest  -p 9000:80 -d nginx

docker run --name nginxtest  -p 9000:80 -d nginx
bf28824643ed39c054e80750b28e5b0d093d62663394851aba9027393d286efe

nginx 启动成功

进入容器内部并去宿主机进行挂载

[root@ysl ~]# docker exec -it  bf28824643ed /bin/bash

[root@ysl ~]# docker exec -it  bf28824643ed /bin/bash
root@bf28824643ed:/# ls
bin  boot  dev	docker-entrypoint.d  docker-entrypoint.sh  etc	home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
root@bf28824643ed:/# cat /etc/nginx/nginx.conf #查看nginx配置文件

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn; #Nginx 日志存放位置
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;  # 引入了 /etc/nginx/conf.d/ 文件下所有的配置文件 
}
root@bf28824643ed:/#   

这个配置文件可以看出 
nginx的日志文件在 /var/log/nginx 目录下
很重要的一点 最后一行 引入了 /etc/nginx/conf.d/ 文件下所有的配置文件 
通过查看default.conf 文件的信息 默认的页面路径 /usr/share/nginx/html

回到宿主机 exit

[root@ysl nginx]# docker run --name DockerNginx -p 9000:80 -v /var/docker/nginx/config/nginx/:/etc/nginx -v /var/docker/nginx/project/dist:/usr/share/nginx/html -v /var/docker/nginx/logs/:/var/log/nginx -d nginx

2. 退出容器 创建需要挂载文件夹

root@bf28824643ed:/# exit
exit
[root@ysl ~]# cd /var/
[root@ysl var]# mkdir docker
[root@ysl var]# cd docker
[root@ysl docker]# mkdir nginx
[root@ysl docker]# cd nginx/
[root@ysl nginx]# mkdir config
[root@ysl nginx]# mkdir project
[root@ysl nginx]# mkdir logs

3. 将nginx容器中的一些配置信息 挂载到刚创建的对应目录中去

[root@ysl nginx]# docker cp 容器id:/etc/nginx /var/docker/nginx/config/
[root@ysl nginx]# docker cp 容器id:/var/log/nginx /var/docker/nginx/logs/
[root@ysl nginx]# docker cp 容器id:/usr/share/nginx/html /var/docker/nginx/project/dist

4. 删除刚刚创建的容器

[root@ysl nginx]# docker rm -f nginx
Error: No such container: nginx
[root@ysl nginx]# docker rm -f 容器id

5. 启动容器

[root@ysl nginx]# docker run --name DockerNginx -p 9000:80 -v /var/docker/nginx/config/nginx/:/etc/nginx -v /var/docker/nginx/project/dist:/usr/share/nginx/html -v /var/docker/nginx/logs/:/var/log/nginx -d nginx

在挂载启动容器的时候很容易犯的错误就是挂载的时候，路径没有指定对，这样的话容器会启动不起来

只要没启动起来八成都是挂载指定配置文件的原因

测试

部署项目

> 在再次部署项目时，需要重新启动下容器，不然会包403错误
>
> ```shell
> docker restart 容器id
> ```
